Lots of people dislike Behringer's mixers. Their quality control is iffy. The preamps can be noisy. The channels can crosstalk. It's definitely low-end equipment.
That being said, I have
a MX802. Why? Cuz I needed a little board and I had little cake to spend. The first unit I got was unadulterated junk-- all sorts of QC issues and VERY hissy preamps. After I took it back I tried another unit, and it was of much better build quality, the preamps are quieter and usable (but certainly not thick or rich sounding), and the phantom power actually shuts off when switched off!
I also usually do only one track at a time, so crosstalk isn't (yet) an issue for me. And noone is paying me to record them either
You can get a usable unit for sure, but it might not be the first one you buy. And pay no attention to the level meters, they bear next to no relation to reality-- things distort/clip out in the low orange!!??! That might make drums a challenge. Also, note that Behringer preamps really suck as bass guitar DIs. (The infamous ART Tube MP utterly smokes it in the bass guitar department.)
Most people will recommend saving another hundred or so and getting a little Mackie VLZ board.
Hope this helps.
Curiosity question: Why do you want to run your VCR and turntable through it? Is the mixer for recording or for your home stereo setup? Do you really want to tear down your stereo every time you want to record?
Also: Don't post the same question in every forum... that will make some people quite testy!
